Water tank sealing in Bani Malik Jeddah
Bani Malik is an old commercial quarter combining historic popular neighbourhoods, the renowned Bani Malik market and a car workshop zone. The area was once a village outside the old Jeddah wall known as Nazlat Bani Malik. Tanks here are very old and set in mixed residential-commercial-industrial use, suffering from corrosion and continuous pressure.

A first-draw flush
We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

Why the job is different in Bani Malik
Buildings here are very old with tanks of widely spaced construction dates, ranging from old clay tanks to concrete tanks from the 1960s and 1970s. The method is set out in full on Water tank sealing in detail.
Tanks in mixed environment with severe corrosion
Workshops and retail shops create a polluted environment with smoke, oil mist and chemical vapours. Tanks corrode inside and out from water quality and industrial pollution.
Old buried piping and connections under the streets
Bani Malik is old and pipes lie buried since decades. Metal pipes are corroded and concrete pipes cracked; tank fittings may be lost or damaged.
Heavy concentrated use from market and workshops
Market and workshops create sustained water demand and very high tank pressure. Heavy daily use causes rapid wear and frequent leaks.
Landmarks of Bani Malik
Bani Malik lies between King Fahd Road and Haramain Road, with the historic district trace back to the old Nazlat Bani Malik settlement outside the wall. The traditional market and workshop belt define the service location and access scope.

What we read before any material is opened
Historic popular quarters and the traditional Bani Malik market, together with a car workshop zone, between King Fahd Road and Haramain Road. Once a settlement outside the old wall known as Nazlat Bani Malik.
Cracking in the wall
Rapid external corrosion is caused by smoke, oil mist and chemical vapours from workshops and retail shops.
The floor to wall joint
The floor-to-wall joint may be missing or damaged in very old tanks, causing continuous seepage.
The condition of the old lining
Pipe entries and drain openings may be corroded or have lost seals; leaks occur from these old points.
Sediment and scale
Standing moisture and water may surround the tank from chronic leaks and old drainage.
The pipe entries
Very old clay tank structures may be fundamentally weak and unable to handle modern pressure.
The hatch and the vent
Leaks and corrosion happen year-round from continuous use, high pressure and industrial pollution.
How we work
-
1
Inspect with the tank empty
We drain it and read the surface dry: whether the water leaves through a crack, a joint or a pipe collar, and what the outer face of the wall and the ceiling below are telling us. A level test with the valves closed separates a leaking tank from leaking pipework.
-
2
Clean and prepare the substrate
Sediment out, a high pressure wash, the loose old lining and the weak surface layer of the concrete taken back, then dried. The material grips sound substrate and nothing else.
-
3
Make the cracks and joints good
Cracks are chased out and filled with a repair mortar, a cove is formed where the floor meets the wall, and every pipe collar is treated on its own.
-
4
Lining, fill test, sterilisation
Successive coats, each run across the one beneath it, on the face the water touches. Then a full cure, a fill with the level watched, and sterilisation with the first fill run to waste before the tank returns to use.
What water tank sealing includes
-
Finding where the water leaves
Carried out drained and dry: cracks, joints, pipe collars and the outer face of the wall.
-
Draining and sediment removal
The last of the water and the settled layer on the floor come out, because a lining does not stick over sediment.
-
Cracks and joints made good
The crack opened and filled, a cove formed at the floor to wall junction, and each pipe entry worked separately.
-
Lining coats on the water face
More than one coat, each crossing the one below, in material made for drinking water tanks rather than roof waterproofing.
-
Curing, fill test and sterilisation
The material is left to cure, the tank is filled and the level watched, then sterilised and the first fill run to waste. How long the cure takes follows the material and the weather, and we tell you before the date so you can plan around the supply.
-
A follow-up level check
We come back once it is in service to read the level and check the outer face, because any remaining loss shows up then rather than on the day of the work.
What is different about Al Sharafiyah Sub-Municipality
The Al Sharafiyah sub municipality runs across central Jeddah from Al Ruwais near the Corniche eastwards through Al Sharafiyah, Al Wurud and Bani Malik to Al Naseem at the Haramain Road. It was among the first areas to grow beyond the old wall, and it is dominated by dense apartment blocks over shops along King Fahd Road and Palestine Street, with old popular quarters, the Bani Malik market, car workshops and storerooms. Ageing buildings, worn drainage and the refuse of restaurants and markets make cockroaches and rodents the most persistent pests, and humidity rises towards the sea.
Questions about this district
Can very old tanks in Bani Malik be repaired or should they be replaced?
Lining repair can save a tank if the underlying concrete is sound. If concrete is severely corroded, replacement is better.
Why do tanks in the workshops corrode so fast inside and out?
Smoke, oils and chemical vapours corrode the exterior. Inside, water quality in the old quarter causes corrosion from within as well.
Will tank treatment stop leaks from very old buried pipes?
No. Tank treatment stops tank leaks only. Old pipes need separate inspection and may need complete replacement if corroded.
Does new lining protect against the polluted environment around the workshops?
Lining protects the interior, but the exterior may keep corroding from vapours and acids. Additional external protection may be needed if possible.
How often should tanks be inspected in Bani Malik market and workshops due to heavy use?
Heavy use requires inspection every six months minimum. Leaks and corrosion happen fast because of pressure and environment.
Can very old clay tanks be restored to service condition?
Very old clay tanks may not tolerate modern lining. Replacement with a new concrete tank may be preferable.
How much does water tank sealing in Bani Malik cost?
It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Bani Malik.
